UNITED STATES PETER 0. KING, OF VALLEY CITY, DAKOTA. TERRITORY.

SNOW-PLOW.

EPECIFICATION forming part of Letters Patent No.321,301, dated June 30,1885.

Application filed June 11, 1884. (No model.)

To all whom it may concern.-

Be it known that 1, PETER 0. KING, of Valley City, county of Barnes, Territory of Dakota, have invented a new and Improved Snow- Plow, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved snow-plow which takes up the snow in several layers simultaneously,

whereby less resistance is offered in forcing the plow through the snow.

The invention consists in a snow-plow provided with a series of inclined ways, one an ranged behind the other from front to rear, which ways have outwardly-inclined wings at the lower ends, and guards or wings at the upper ends on the roof of the car. The lower ends of the ways are arranged at different ele vations above the tracks.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a longitudinal elevation of my 3 improved snow-plow, parts being broken out 1 Fig. 2 is a plan 1 and others shownin section. view of the same. Fig. 3 is a sectional plan view of part of the same on the line a, Fig. 1.

A box'car, A, or fiat car is provided at its front end with two or more inclined ways or B,V-shaped guards or wings F are formed on the top of the car, the said wings having concaved fronts or being curved outward from the bottom to the top. The roof G of the rear part of the box-car is peaked, so that the snow will slide from the same more readily. The rear part of the boxcar can be used for carrying implements, &c., and can also be used as a car for laborers. The wheels J are all arranged behind the inclined ways.

The operation is as follows: vvhen the plow is forced through the snow, the snow that is removed is carried up by the inclines'D B B at the same time, and passes from the upper ends of the inclines down over the sides of the car. The snow is guided to the sides of the car by the guides F, which also prevent it from clogging the following inclines. The three inclines remove the snow at three different elevations from the track-that is, a horizontal layer of snow is removed by each incline, the front incline removing the uppermost lay er. The wings H guidethc snow into the bottoms of the chutes or inclines. As the snow is removed in three layers, the resistance offered to the plow is reduced materially, and less power is required to force'the plow through the snow.

The openings through which the snow passes from the bottom to the top of the plow can be made of uniform width, or they can increase in width from the lower to the upper ends.

The inclines can all be made flat, as shown, or they can be peaked like a locomotive cowcatcher.

Having thus described myinvention, I claim as new and desire to secure by Letters Patent 1. A snow-plow provided with a series of inclined ways, one arranged behind the other from front to rear, the distance from the lower end of each inclined way to the track gradually increasing toward the front, said ways having wings at their lower ends and sides, substantially as herein shown and described.

2. A snow-plow having a series of inclined ways, each provided with wings H at the lower ends and sides, substantially as herein shown and described.

3. A snow-plow having an inclined way, D, at its front end, and wings E at the sides of the inclined way, the inclined ways B, the bottom wings, H, and the top wings or guards, F, substantially as herein shown and described.

PETER 0. KING.
